<br />is incorrect and Core Labs will issue a corrected sheet. <br />Corrected data sheets indicating the use of hydrochloric acid have <br />been added to Appendix F 4/20/89. <br />MLRD Comment 41. <br />Response: Pond stability analyses are included with this submittal. <br />The minimum static and psuedostatic factors of safety are 1.5 and <br />1.1, respectively. As the factors of safety are equal to or greater <br />than the minimum factors required by the U.S. Army Corps of <br />Engineers for earth and rockfill dams, the solution ponds are <br />stable structures. The minimum values required by the U.S. Army <br />Corps of Engineers are 1.5 and 1.0 for static and pseudostatic <br />analyses, respectively. <br />Leach pad pond stability analyses section D.7.6 added to Exhibit <br />D 4/20/89. <br />1 ML^D Comment 46. <br />Response: As shown on the enclosed revised water balance table, <br />only relatively minor net evaporation losses can be realized in the <br />final two to three months of operations. The water balance table <br />shows that during this time water from the leaching operations will <br />be pumped to the mill for use as make up water in the milling <br />I operations. Since the mill will continue to operate for 6 to 8 <br />months after leaching operations are completed, the ponds will be <br />drawn down to maximize the winter storage prior to the commencement <br />' of rinsing the following spring. During rinsing, if water levels <br />in the pond indicate a need for controlled release through land <br />application, BMR will submit a technical revision to the MLRD for <br />approval detailing how the land application will be accomplished. <br />Appendix G Water Balance has been revised 2/22/89. <br />MLRD Comment 59. <br />Response: BMR commits to submitting an Emergency Response Plan to <br />the MLRD prior to bringing any potentially hazardous chemicals on <br />to the site. <br />Emergency Response Plan incorporated into the permit application <br />as Appendix P x/20/89. <br />MLRD Comment Reclamation Plan. <br />Response: BMR will maximize the wildlife access to the postmining <br />West Pit area through the use of land shaping techniques. Such land <br />shaping will include man made talus slopes placed at the angle of <br />repose and walked with a dozer to ensure stability. These slopes <br />will allow access between the benches for wildlife and will be <br />placed at irregular intervals throughout the pit. In addition, <br />j several of the access ramps from bench to bench will be left in <br /> <br />
